A pastor and independent miner in Sierra Leone has unearthed an uncut 706-carat diamond estimated to be worth tens of millions of dollars. The pastor turned the diamond over to the government in hopes that the proceeds from its sale will help the impoverished country. But given the history of this former "blood-diamond" nation, what happens from here is anyone's guess.

Video: When you win a championship as a professional athlete, you get a ring. But it isn't a normal ring meant for normal humans with normal fingers. No, championship rings are enormously gaudy boulders with, like, a million diamonds set in a very specific way because it represents winning or something. The excess is impressive and I love it.

It is not pleasant inside the core of Jupiter -- or any other planet for that matter. However, gaining a better understanding of what's going on in there is key for understanding how these planets form. That's why a team of scientists at Lawrence Livermore National Laboratory recently used diamonds and lasers to recreate those very conditions.

It's no surprise that the diamond industry is willing to spend whatever it takes to make the process of mining precious gems even more profitable. And while it already relies on X-ray technology for spotting diamonds on the surface of mined ore, researchers at the Fraunhofer Institute's Development Center for X-ray Technology EZRT have developed a way to now spot them buried inside rocks.

Since graphite -- the dark material used in regular old pencils -- and diamonds are both made from carbon, it's technically feasible to turn the former into the latter. You just need to apply a little pressure -- about 150,000 times what the atmosphere on Earth's surface is like. But researchers at Stanford University claim to have found a shortcut.

The jewellery market has been flooded with synthetic stones over the last several years; not just lab-grown gems but flat-out fakes. Here's how to tell if your rock is the real McCoy and not just a shiny bauble.

Hold on to your engagement rings. Diamonds, according to an industry report, are falling off a supply cliff in 2018. As existing diamond mines are depleted even as worldwide demand increases -- thanks, especially to a newly rich Asia -- three months' salary might soon buy you a much punier rock.

We're a little late to the party on this one, but it's just too fascinating to pass up. A team of planetary scientists recently claimed that the mix of methane, carbon and lightning in Saturn's atmosphere is causing diamonds to be forged in the planet's atmosphere. Like, a lot of diamonds.
